Abstract: Since the current vehicle audio system has a defect that the function of the system is limited and it is difficult to update media files for the system, the design and implementation of a high-performance vehicle player that can play both audio and video media files were given. The latest embedded processor Atom Z510 published by Intel was selected as the core processor of the system, XPE (Windows XP Embedded) was built on it, and Qt-Creator was used to design the software of the player, Graphical User Interface (GUI) technology was also used to design a graphical user interface for the player. The player can not only play local media files, but also identify the CF card, U disk and other removable storage devices and play media files stored on them.

Key words: vehicle player, Graphical User Interface (GUI), Atom Z510 processor, Windows XP Embedded (XPE)

摘要： 针对现有车载影音系统功能单一、更新不便的缺陷，设计并实现了一款能够同时实现音频和视频播放的高性能车载播放器。系统采用Intel最新推出的嵌入式处理器Atom Z510作核心处理器，在其上定制XPE作操作系统，采用Qt Creator作开发工具，使用图形用户接口(GUI)技术，实现了一个带有图形操作界面的播放器。该播放器既能播放本地媒体文件，也能识别CF卡、U盘等移动存储设备，并能对移动设备上存储的媒体文件进行播放。
